摘要： Connecting rod ultrasonic-assisted splitting machining method and a machining device thereof, relating to the field of machining of a connecting rod. The machining device comprises a rack, a fixing block, a sliding block, a sliding block base, a vertical locking oil cylinder, a wedge-shaped pull rod, an adjusting block body, etc. By means of the method and the device thereof, the range of the material used for splitting the connecting rod is enlarged, the splitting force required during the splitting of the connecting rod, deformation of fracture surfaces, residues generated during the splitting process, out-of-roundness of big end holes of the connecting rod, and other situations are reduced, and the engaging accuracy of the connecting rod and the joint face of a connecting rod cover and the assembly quality of the connecting rod are improved.
